The Hach 2586sc Oxygen Scavenger Analyser is the optimal solution for monitoring hydrazine and carbohydrazide levels in water systems, ensuring optimal performance and reliability. This advanced analyser is essential for maintaining the efficiency of oxygen scavengers, particularly in the power industry, where it plays a crucial role in protecting water systems from oxygen-related corrosion. Featuring the state-of-the-art SC4500 Controller, the 2586sc offers enhanced precision and user-friendly operation that surpasses that of its predecessor, the SC200. The 2586sc is the indispensable tool the power industry needs to safeguard their critical water systems. Its robust design and cutting-edge technology provide accurate and real-time monitoring of hydrazine and carbohydrazide. The Hach Polymetron 2586sc analyser continuously measures the amount of oxygen scavengers, dissolved hydrazine, and carbohydrazide in water with precision and reliability. The measuring principle is based on the electrochemical method of 3-electrode amperometry. The 9586 sc Oxygen scavenger analyser has a fast response time of less than 60 seconds. Unlike traditional amperometric techniques that use two electrodes, the 9586 sc uses a three-electrode design; eliminating voltage drift due to the composition of the water. The working electrode self-cleans by turning PTFE beads. Calibrations are done via comparison method.
